Submillimeter-band high-power generation using multilayered Josephson junctions

We report on numerical simulations of 10- and 19-layer stacked Josephson junctions. Simulations are performed using the experimentally feasible parameters for Nb/Al–AlOx/Nb junctions. With an appropriate choice of parameters such as magnetic field and coupling, the current–voltage curves of N-layer...

description We report on numerical simulations of 10- and 19-layer stacked Josephson junctions. Simulations are performed using the experimentally feasible parameters for Nb/Al–AlOx/Nb junctions. With an appropriate choice of parameters such as magnetic field and coupling, the current–voltage curves of N-layer stacks systematically indicate in-phase locking among the inner N−2 junctions. The simulation results suggest that multilayer Josephson junctions are very promising as submillimeter-band high-power oscillators.
